INSOLE.

Specification of Letters Patent.

Patented July 11, 1916.

Original application filed September 18, 1911, Serial No. 650,020. Renewed March 5, 1914. Serial No. 822,767. Divided and this application filed July 19, 1915. Serial No. 40,662.

To all whom it may concern:

Be it known that I, JAMES E. JACKSON, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Insoles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to insoles.

More particularly the invention relates to a novel reinforced insole.

The insole of the present application and a machine for performing one of the steps in the process of its manufacture are disclosed in applicants application for Letters Patent of the United States filed originally September 18, 1911, Serial No. 650,020, and renewed March 5, 1914, Serial No. 822,767 (Patent No. 1,162,721, dated November 30, 1915,) from which original application this present application is a division.

In the early life of reinforced insoles the type having the greatest commercial success was the Gem disclosed in the patent to Cole No. 575,460, dated January 19, 1897. Later other types of reinforced insoles Were developed such as the Economy disclosed in the patent to Johnson No. 849,245, dated April 2, 1907, and the W'onder-Torker disclosed in the patent to Ryan No. 958,013, dated May 7, 1910, and tosome extent in the earlier patents to Krippendorf No. 579,518, dated March 23, 1897 and Bohr No. 878,453, dated February 4, 1908. The Gem insole was a better insole than the Rochester insole disclosed in the patent to ltioore No. 275,248, dated April 3, 1883, which preceded it, because in the Gem the reinforcing fabric is carried across the feather, thus stiffening this exceedingly flexible portion of the insole and preventing its becoming curled up under the upper in the lasting and subsequent operation on the shoe. For this reason, also, the commercial supremacy of the Gem insole has been generally maintained since the introduction of the Economy type of reinforced insole because this type is open to the same criticism as the Rochester insole, that is, an unreinforced feather is used, which is a serious defect on thin stock. At the same time the Economy insole is an improvement on the Gem insole because of the greater strength of the marginal lip or rib and because the stock at both the inside and outside of the lip is of the same thickness, making for a tighter seam and for less damage to the reinforcing fabric during the inseaming operation, as is well understood by those skilled in the art. Another, and a serious, defect in the Gem insole, which the later types of reinforced insoles overcome, is that the duck or canvas, used as reinforcing fabric, is trimmed in such manner that its raveled edge shows beyond the edge of the insole and gives an unsightly appearance to the inside of the finished shoe. It has more recently been proposed to combine some of the good features of the Economy and Gem insoles in a single insole and some manufacturers are now using an insole blank having a marginal lip or rib like that of the Economy insole and a sheet of reinforcing fabric applied thereto like that of the Gem insole. An illustration of this type is found in Figure 3 of the Thoma Patent No. 1,108,026, dated August 18, 1914. Still this reinforced insole, which may be termed the Cincinnati insole is imperfect because it does not overcome the serious defeet of the fabric showing. at the shank of the insole especially, in the finished shoe.

The object of the present invention is to produce a reinforced insole, which overcomes all of the defects present in reinforced insoles heretofore adverted to.

To the accomplishment of this object, the invention comprises an insole blank having a marginal lip or rib, reinforced with suitable fabric in the novel manner hereinafter indicated.

An understanding of the invention will be assisted by reference to the accompanying drawing in which,

Fig. 1 is a transverse section across the forepart of an insole blank with its edge slit as is customary in making :1 Gem insole; Fig. 2 is a transverse section across the forepart of the insole blank of Fig. 1 with the marginal lip upstanding and reinforcing fabric applied to its lipped face; and Fig. 3

is a transverse section across the, shank of the insole of Fig. 2 after having been operated on by the present novel method.

In making the insole, the blank 2 which may be of leather or any other suitable material, is preferably slit at its edge as at 4 (Fig. 1) in a plane usually parallel to the face of the blank. The section 6,.on the flesh side if the blank is of leather, is then upturned to form a marginal lip or rib (see Fig. 2) while the section 8, on the opposite or grain side of a leather blank, forms the feather of the insole. Reinforcing fabric 10 which is preferably, although not necessarily, in the form of a wide sheet. is then applied to the lipped face of the blank 2, being beaded or crimped about the lip or rib 6 and extending laterally to either side thereof. The fabric may be applied by hand, or by any of the commercial machines supplied for performing this operation, and if applied by a machine the fabric, if it projects beyond the edge of the blank, may be simultaneously trimmed alonga line coinciding with the edge of the blank, as shown in Fig. 2. It will be understood that the reinforcing fabric, now generally used, is of the prepared type, that is, provided with a cementitious coating which when cool is dry but which becomes tacky when heated, and it is applied to the blank while in its heated condition. The first application of the fabric seldom causes the fabric to lie snugly in the angles at the outer and inner sides of the lip or rib and, therefore, a rib tightening operation on the reinforced blank is very generaly performed. The machine of the parent application. from which the present application has been divided, is preferably used to perform this rib tightening operation and the insole is passed through this machine while the fabric is still hot, that is, before the cementitious coating has had time to become set and hold the fabric firmly to the blank. This rib tightening machine, as fully described in the present application. has tools for pressing on the fabric in the angles at both sides of the lip or rib and causing it to lie snugly against the blank at these points. The rib tightening tools are also so shaped as to give .the reinforced lip or rib an inward set or bend, as shown in Fig. 3 for a purpose hereinafter explained. Furthermore, this rib tightening machine is provided with means to consolidate the stock at the inside of the lip or rib, forming a channel at this point,

leaves the feather of the same thickness as existed before the application of the fabric and, therefore, unweakened. In other words, the insole on completion has an un reduced feather, because in performing the last named step in its manufacture, there is no reduction or thinning of any part of the feather stock. It will be obvious to those skilled in the art, however, that the use of the machine of the parent application is not essential in producing the novel insole her inafter defined by the broader claims, as anyv suitable or convenient means or machine may be utilized to produce the channel at the innerside of the lip or rib, to bend the lip or rib inward, or to remove the fabric from the outer margin of the feather to cause its edge to lie within the edge of the blank. As a result of this method of making reinforced insoles the insole produced is possessed of all the features of advantage hcreinbefore adverted to, namely: the lip or rib is sufficiently strengthened. for receivingthe inseam, by two layers of fabric; the stock at both sides of the lip or rib is of the same thickness. providing for a tight seam; the fabric is removed from the outer margin of the feather so that it is not visible when the insole is attached to the upper: and the lip or rib is bent inwardly so as to provide a firm support for the channel guide of the welt sewing machine and enable the shoe to be easily held in proper position to receive the inseam stitches.

I believe myself to be the first to produce a reinforced insole with the reinforcing fabric so applied and shaped as to render it invisible on examining the insole after having been incorporated in a shoe. The shank portion of the insole is its only portion plainly visible on looking into the completed shoe and. therefore, it will be obvious that the fact that thereinforcing fabric on parts of the insole other than the shank is or is not invisible is immaterial, the true scope of the invention being found defined in the appended claims.

The nature and scope of the invention having been indicated and its preferred embodiment having been specifically described, what is claimed as new, is
